T 0 all whom it may concern:

Be it known that I, THOMAS H. SnELY, a citizen of the United States, residing at Malden, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Fastening-Inserting Mechanism for Lasting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like referencecharacters on the drawings indicating like parts in the several figures.- V

The invention to be hereinafter described relates to machines for manufacturing boots and shoes, and more particularly, though not exclusively, to lasting machines whereby the upper materials are worked over a last and innersole and secured either permanently or temporarily in lasted position. Broadly considered, the invention is not confined for use in connection with any particular type of lastingmachine, but for the purpose of making-clear its construction and mode of operation, it will herein be described as associated with that class of machines in which the upper materials are worked into lasted position by repeated operations on difierent portions and secured by fastenings driven through the overworked portions as the work progresses. A machine of this general character is shown anddescribed in United States Letters Patent No. 584L744, dated June 15, 1897. I

In lasting welt shoes, it'is the custom to fully drive small fastenings or tacks through the marginal portions of the overworked upper and ears of the counter, orit may be about the entire heel seat to permanently secure the upper in lasted'positi'on, but at other portions of the shoe, longer fastenings are partially driven to temporarily hold the upper in overworked or lasted position until after or during the welt-attaching operation, when they are withdrawn. In lasting McKay shoes, the fastenings are or may be fully driven around the entire shoe to permanently secure-the upper in overworked or lasted position, butin such case at the toe and heel seat portions of the shoe, longer tacks are required than at other portions of the shoegowing to the increased thickness of the upper materials through-'which the fastenings are driven. Thus, in thelasting operation, whether upon a welt or'McKa'y shoe, a change in the character, kind, or size of the fastenings furnished must be made from time to time. I

Heretofore, it has been the custom toprovide a fastening-supplying means usually in the form of'a raceway having two or more channels orguides each supplying a different character,kind, or size of fastening and to place one or the other of such channels or guidesin operative relation with a separating mechanism for supplying the desired fastening to a nail blockby which the fastening was placed in inserting position. In this prior construction, however, the first fastening presented to the insertingmechanism or driver after a change of'the raceway to place the desired channel or'guide in supplying position, was of the character, kind, or size previously in use, and consequently not suited to the new portion of the shoe presented for treatment. It has therefore been necessary for the attendant or operative to run the machine idle or without a shoe for at least one cycle of operation after a change has been made in the character, kind, or size of the fastenings to be used, thus causing loss of one or more fasteni-ngs after each change, lack'of economy in the machine operation, and an accumulation of loose fastenings on the floor.

An important feature ofthe present in-.

vention, therefore, consists in means for se lectively presenting the desired character, kind, orsize of faste-nings to the inserting mechanism including the first fastening pre sented after a change has been made bythe supplying means in the character, kind, or size of the fastenings to be supplied by it.

In accordance with this feature of the invention a receiving means or member is provided between a plurality of sources of tack supply fortacks of different kinds and the inserting mechanism which means is arranged to receive and hold a separated tack of each of the different kinds and means under control of the operator is provided to determine which of the separated tacks will be delivered to the inserting mechanism. c

As herein shown the receiving means com prises a presenter'located" between the separating mechanism and tack block and hav ing a plurality of pockets, the presenter being movable in different paths in accordance with the character, kind, or size of fastening supplied by the supplying means, to position one or another pocket in line with the inserting mechanism or driver.

7 further feature of the invention consists in a plurality of sources of tack supply, for example raceways, for different kinds of tacks, a separator for separating tacks from the source of supply, and means, for 'eX- ample the presenter referred to, for receiving a tack of each kind from the separator.

In some kinds of shoes, the fastenings inserted in the heel seat or through the ears of the counter are located further from the edge of the shoe than are'the fastenings at other parts of the shoe in order that the V the position of the shoerelative to the path of the inserting means or driver be changed correspondingly that the'particular fastenings to be inserted be located the desired distance from the edge of the shoe. An other important feature of the invention, therefore, consists of movable work rests or gages which are moved relatively to present the proper'rest or gage to the shoe simultaneously with the change in the character, kind, or size of the fastenings to be furnished by the supplying means so that the first, as well as the succeeding operations of the inserting mechanism may insert proper fastenings at the desired distance from the edge of the shoe.

Upon the completion of one shoe, the attendant or operative usually maintains his foot upon the starting treadle while he reaches for another shoe, and the machine consequently continues in operation. During this interval a loss of fastenmgs occurs because there is no shoe positioned in the machine to receive them. It has therefore been proposed to suspend the operation of the fastening-separating mechanism when l a shoe is, not presented to the machine for treatment, but the fastening carrier or tack block, as it is usually termed, was moved to driving position and if the driver remained in operation, it would expel any fastening contained in the pocket of the carrier or tack block, with the result that no fastening would be presented to the driver on its first action after another shoe was present ed for treatment. Another important feature of the present invention, therefore, consists of means for causing the fasteningpresenting mechanism to retain the fastenercarrying pocket away from the action of the inserting mechanism when a shoe fails-to be in position for treatment during the operation of the machine. This feature of the invention is carried into efiect by a presenter which, during the operation of the machine when a shoe is positioned for treatment, carries a fastening from' the separating mechanism to driving position, but which, during the operation of the machine without a shoe to receive the fastenings, does not move the fastening to driving position. This is advantageous because, among other things, it obviates, the necessity of some means for suspending the operation of the driver when a shoe is not in position for treatment and yet insures the presentaticn'of a fastening t the first action of the driver when a shoe is placed in the machine.

It is usual in machines of this type to shift the raceway in order to bring one or another guide or channel in line with the opening in the block of the separating mechanism. Much care and attention have therefore been required in constructing these parts in order that they, might be properly co-related and relatively moved. A further important feature of the present invention consists in adjustable connections between the raceway and its moving means for changing the path of raceway movement and the amplitude or extent of such movement. As a result, the raceway parts may be made with less accuracy and pre-' cision as to details, and then co-related with the block of the separatingmechanism to bring the guides or channels in proper position when the raceway is shifted.

The above and other features of the invention will be hereinafter described inc nnection with the accompanying drawings showing one good, practical form thereof, and the novel features will then be definitely defined by the claims.

In the drawings:

Fig. 10 is a view similar to that of Fig. 9, showing the same parts in another posi tion and the presenter delivering a tack to driving position.

The machine frame comprises a column or standard 1 on which rests the head 2 for supporting the operating parts, and as usual in such machines, a treadle rod 3 extends downward from the head for starting and stopping the machine operation. The head 2 supports a cam shaft 4 which may be driven from a pulley 5 operated by belt connection with a suitable source of power, as usual. The shaft 4 has connected therewith a cam 6 for operating the grippers, a cam 7, Fig. 3, for lifting the driver-bar 8, and a cam 9 for operating the tack carrier slide 10. A spring impelled arm 11, Fig. 1, acts to impel the driver bar 8 and driver 12 downwardly for inserting or driving the fastenings into the work. The parts so far described mav be of the usual construction and operation.

The machine illustrated is more particularly designed to treat welt shoes, wherein it is customary to partly drive long fastenings or tacks along the sidesand fully drive shorter fastenings or tacks through the ears of the counter or about the heel seat. The driver-bar 8, therefore, has a collar 13 adapted to stop the downward movement of the driver by engagement with stops 14 when long tacks are to be partly driven, but permit full downward movement of the driver when the stops 14 are withdrawn that the shorter tacks may be fully driven.

The stops 14 are operatively connected to the shaft 15, which, as will more fully ap pear, is turned by means under control of the attendant to place the stops 14 in or out of operative position in conformity with the character of tacks to be driven. Herein, the terms fastenings and tacks are used in the broad sense, to designate devices which are separately or independently inserted or driven into the work.

The slide 10 has a front portion 16 from which extends the tack-block 17, Fig. 4, the lower surface 18 of which constitutes a wiper to wipe or lay the marginal portions of the upper materials over the innersole of a shoe presented for treatment. The

:front portion of the tack-block has a driver passage 19 through which the driver 12 passes and forces a tack into the work during the tack-driving operation. Between the upper and lower surfaces of the tack block at each side thereof, a recess is formed for'the accommodation of the tackguiding springs 20, which may be of usual construction. The tack-block preferably has its ened steel secured thereto by means such as the pin 21 and bolt 22, Fig. 4.

The fastening or tack-supplying means consists of a raceway 23, Figs. 2 and 3, having in the present instance two guides or channels 24 and 25 for supplying different kinds 01- sizes of tacks, and the raceway is adapted to be shifted to place either guide or channel in operative relation with the receiving opening of a tack-guide or separator block 26, as is customary. Cooperating with the tack-guide 26 is the separator 27 provided with a tack-separating slot, as usual, and reciprocated in front of the raceway by the toothed segment 28 pivotally mounted at 29 and yieldingly connected to an arm 30 carrying a roll 31 adapted to be Pivotally mounted on the swing plate 35 at 36 is an arm 37 by which tacks separated from the supplying means are individually transported or presented to tack-driving position above the driver passage 19 in the tack-block. For the purpose of identification, this arm 37 may be designated a presenter, because it takes the desired fastenings from the separating mechanism and de livers or presents them to driving position. In the present instance, the presenter is 10- cated between the swing plate 35 and the tackblock and is provided with two tackholding pockets corresponding to the number of guides or channels in the raceway or the number of different kinds or sizes of tacks to be supplied. The tack-holding pockets may be variously contrived, but as more clearly shown in Fig. 6, they are preferably formed by three blocks 38, 39 and 40 each having complemental portions of a tack-holding pocket and detachably held in the end portion of the presenter 37. The presenter 37 in the present instance is split longitudinally for a part of its length, as at 41, to form two spring arms 42 and 43, and the blocks 38, 39 and 40 have interlocked shank portions 44, 45 and 46, which are irregularly-formed as shown, and 00- related with each other and the spring side arms of the presenter, the construction being such that while the blocks or tack-pockets may be appropriately secured to the presenter, they may yield or separate slightly to permit the tacks to be driven and may also be readily removed when desired.

The presenter 37 has a rearward extension 47 to which is connected at 48 a link 49 which,,under the means to be hereinafter described, serves to control the path of carrying a roll 53 movement of the presenter and determine thereby which of the two tack-pockets 50, 51, shall be moved into position above the driver passage 19 in the tack-block when the parts are in position to deliver a tack the inserting mechanism. The rear extens on of the presenter is in the present instance formed to embrace the portion 16 of the tack carrier slide and the embracing portion thereof is sufiicicntly large to permit swinging movement of the presenter by the link 49, as will more fully appear.

The swing plate is under the influence of a spring which normally holds the swing plate and perforce the presenter pivoted thereto in rearward position relative to the tack-block, as indicated in Fig. 2. In the present instance of the invention, the swing plate has projecting therefrom an arm 52 against which the spring secured to the slide bears, the construction being such that the pressure of the spring 54 against the roll 58 normally holds the swing plate and presenter 3'? in rearward position, as described.

Secured to the shaft 15 by suitable means such as the clamps 55 and bolts 56, 2, is a casting 57. The casting 5'? has connected thereto ahandle 58 by which the casting 57 and shaft 15 connected thereto may be rocked from time to time, as desired. In the present instance of the invention the handle 58 has a portion 59 carried by lugs 60 projecting from the casting, and extending upwardly from the portion 59 are the wings 61 which, as more clearly indicated in Fig. 8, may be constituted as looking lugs, the end portions 62 of which'are adapted to ride along surfaces 63 and engage the looking recesses 6d at either end of the handle movement. Pivotally mounted at 65 in a suitable bracket 68 are the arms 66 connected by a spring 67 as indicated in Fig. 8, to insure locking engagement of the locking lugs or wings 61 with either of the locking recesses 64. The above-described construction is a good, practical form of attendantcontrolled means for swinging or rocking the casting 57 and shaft 15, but obviously the details of this construction may be varied within .wide limits without departing from the spirit of the invention. As

hereinbefore described, the rear portion of the presenter 37 is connected to a link if) for controlling the movements of the presenter. In the present instance of the invention, the link 49 is pivotally connected at 69 to the casting or part 57 which is rocked by the hand-piece 58, the construction being such that by moving the hand-piece 58 into the one or the other of its positions, as indicated in Fig. 8, the rear end port-ion of the pre senter 37 will be moved laterally so that as the nail-block and tack presenter move forwardly and the tack presenter is moved relatively to the tack block, as will more fully appear, either one of the tack-pockets 50 or 51 may be, caused to coincide with or carry a tack into position above the driver passage 19 in the tack block.

'The raceway 23 is alsoconnectedto the hand-piece 58 so that upon movement of the hand-piece, the raceway is moved to bring one or the other of its guides or channels into cooperative relation with the usual opening in the tack-separator block 26 and the tack presenter 3'? is likewise shifted to change its path, of movement and thereafter take from the tack-separating mechanism the desired kind or size of fastening to be inserted into the new portion of the shoe presented for treatment. When moved to one position by the link 49, the tack presenter .37 is adapted to take tacks from the separating mechanism of one kind or size and when shifted to the other position by the link 49, is adaptedto take tacks of the other kind or size from the tack separating mecha-, nism,.the construction being such that when the tack presenter 37 moves forwardly to present a tack to driving position, each of the'pockets 50 and 51 carries a tack or fas toning, one tack or fastening being of one kind or size, and the other tack or fastening being of the other kind or size. When the tack pockets in the presenter are empty for any reason, as for instance when the machine is first started, it will, of course, be necessary to run the machine idly through a cycle or two first with the lever 58 in one position and then with it in the other position, the rest 83 being held up in order to permit tacks to be separated and the tack pockets to be filled. Subsequently, whenever a shift is made in the raceway, and perforce, in the tack presenter, by the attendant, the tack presenter 37 will present a tack of the desired kind or size to the first action of the driver after a change in the kind or size of tacks to be driven. The path of movement of the tack presenter in delivering tacks to driving position by the tack-pocket 51, for instance, is indicated in Fig. 2, wherein the arrowed dotted line represents the path of movement of the pocket 51 from tack-receiving to tack-delivering positions.

When no shoe is presented to the machine for treatment, as for instance, when the attendant finishes one shoe and reaches for an: other, without stopping the machine, 1t'1s' desirable that the presentation of tacks to driving position be suspended. This is parpelled, and on the presentation of a shoe to the machine, the firstaction of the driver would find no tack in position to be driven. The present invention provides means which, when a shoe is not in positionfor treatment, will not move into tack-driving position the next tack to be driven.

The arm or bracket. 70, Fig. 1, has adjustbly secured thereto as by the slot connection 71, an arm 72 to which is connected by parallel link motion devices? 3, the shoe rest carrier 7 1. On of the links 73 is extended upwardly as indicated in Fig. l to form a toe T 5, Figs. 1 and 2, adapted to bear upon the arm 7 6 of a lever pivoted at 77 on the bracket and normally under the influence of a spring 78 which, in the present instance of the invention, is shown (Fig. 2) as constituted by a spring plunger, the head of which'is adapted to bear againstthe side of the lever arm 7 9. The arm 79 carries an adjustable block 80. swing arm is a shouldered lug 81. This may be variously contrived, but in the present instance, comprises a piece formed sepa-' rate from the arm 33 adjustably secured thereto by the bolt 82, the construction and relation of parts being such that if a shoe is not presented to the machine-for treatment, the shoe rest 83 is not raised and the arm 79, under the action of the spring '78, holds the block 80 out of the path of movement of the shouldered lug 81 as the latter moves forwardly with the tack-carrier slide 10, the effect being that the spring 54, acting thru the arm 52, maintains the swing plate 35 in its rearward position relative to the tack block 17, as indicated in Fig. 9, so that as the tack block and, perforce, the swing plate 37, move forwardly with the tack carrier slide, the presenter 37 is not moved relatively to the tack bloc-hand so fails to present one of its tack-holding pockets in position above the driver passage in the nail block, so that the-fastenings or tacks in the pockets of the presenter retherein. On its driving stroke, the driver 12 will pass in front of the-presenter and through the driver passage '19 of the tack block. The position of parts when no shoe is presented to the machine for treatment, is represented in Fig. 9, wherein it will be noted that the tack carrier slide has moved forwardly to place the driver passage 19 of the tack block in driving position, but the presenter 37 carrying tacks in each of its tack-holding pockets, has not been moved relatively to the tack block to present either pocket in driving relationwith the driver passage 19.

When no shoe is presented for treatment during the operation of the machine, i -1S likewise desirable that the tack-separating mechanism be rendered inoperative, and this effected in the present instance of the 1nrention by the cam-carrying arm 32 which,

Rising from the since the swing plate 35 remains in the position indicatedinFig. 9,. isnot swungoutwardly suiliciently far to cause. actuation. of the tack-separating mechanism during the forward. movement of the tack-carrier slide.

When, however, ashoeais presented to the .inachine:fortreatment, .theshoe restw83 is raised-:and-the anm.79 of thepivotedlever ismoved to carry the: block 80 into the path of movement of the shoulderedlugSl as the latter advances with:theHtack-carrier slide 10. On contact of theparts 80.-.and. 81, .the

swing'plate 35 is mo-vedwabout itspivotal presenter may be accurately positioned above the driver passage 19 of the tack block and to this end, the present invention provides in addition to the locking means for the hand-piece 58, a safety devicewhich will preventmovement" of thehand-piece during the time the machine-is operating upon a shoe. To-this end, the arm 79, F i g. 2, is providedwith an inturned portion84 adaptedto engage: the-endportions of a lug 85, :Figs. 2 and 3, extending from the casting 57 when the arm 59 has 'beeni-moved, as I hereinbefore "described, bya shoe presented to the machine for treatment. So longas the shoe is held in the 1 machine, the inturned end 84c ofthe arm79' willremain in the path of movement of the lug 85 and therefore act as-a safety device to prevent manipulation of the hand-piece58while the machine is operating upon a shoe. {Injthe present instance of the invention, the end portion of the lug 85 is preferably formed by a separate piece c'f har'dened metal 86 secured to the lug 1 85 I by appropriate means such as the bolt 87. llerei nbefoi-e it was stated that the raceway '23 was moved to bring either of its guides or channels 24 01 25' into co-operative relation with the-usual opening in the tack-separator block by the hand-piece 58, and to this end the raceway 23 is connected to the'casting 57. The connections inthe present instance of the invention are of '7 novel character and construction, and effect for the first time in the art a ready means of adjusting both the position of the path of movement of the raceway and also its amplitude of movement, so that in the-manufacturing of the parts, the greataccuracy and care heretofore required becomes unnecessary. In the present instance of the invention in this respect, the casting 57 has adjustablysecured thereto .a block 88, Fig. i

3, which, by means of a bolt 89 and slot :90,

may be adjusted to different positions relative to the casting and'then secured in such adjusted position. Extending from the block 88 is a lug 91 to which is pivotally connected at 92, one end of an arm 93, the other end of which carries a sleeve 94: thru which the rod 95 extending from the raceway 23, passes. screw-threaded into the sleeve 94:, as at 96, Fig. 3, and a lock nut 97, Fig. 2, serves to hold the parts in adjusted position. The connectionbetween the rod 95 and the arm 93 may, of course, be variously contrived to afford adjustment in the length of the rod 95 between the arm 98 and the raceway, but thatdescribed has been found to be a good, convenient form of this feature of the invention. By the characterof adjustment last described, one of the guides or channels 24.

or 25 of the raceway 23 may be accurately registered with the opening in the tack-separator block, and by means of the hand being made without disturbing the previous adjustment and the two adjustments serving to adjust the position of the raceway in its path of movement, and the amplitude of such movement.

As hereinbefore indicated, it is desirable portion of the shoe at a different distance from the edge ofthe shoe than fastenings are. driven at another point of the shoe; and to this end two gages areremployed which are technically designated the thin? and the thick gages. The thin gage is usually employed along the shank and forepart of the shoe, while the thick gage is employed about the ends of theshoe as, for instance, at the toe portion and about the heel seat. It therefore becomes necessary to shift the gages simultaneously with a shift in the kind or size of fastening or tackto be supplied.

In the present instance of the invention this feature is carried into effect by the construction more clearly shown in Figs. 2, 3 and 7.

Fixed to but adjustably mounted upon the head frame is the plate 98 having a slot 99 thru which passes the securing bolt 100, the construction being such that the plate 98 may, by loosening the bolt 100, be adjusted bodily toward and from tack driving position. Supported for movement toward and from tack-driving position on the plate 98, isthe gage carrier 101. This sliding connection between the fixed and movable The rod 95 is preferably,

Secured to the shaft 102 is a segment gear 106 which engages the teeth 107 of a rack bar 108 mounted to slide longitudinally. The rack-bar 108 has a seriesof teeth 109 which engage the teeth 110 on a toothed segment 111 which is fixed to the rotatable pin 112. Also fixed to the pin 112 is the arm 113 pivotally connected by the link 114 to the casting 57 as indicated in Figs. 2 and 8. In the present instance of the invention, the casting 57 has a downwardly-extending portion 115 to which is pivotally connected at 116 the link 114. p

The pin 112 is mounted in the gage carrier slide 101 and has adjustably'secured thereto the block or projection 117, Fig. 7, the end portion 118 of which is adapted to engage an inclined slot or opening 119 formed in the fixed plate 98, the construction being such that upon manipulation of the hand-piece 58, movement will be imparted to the gage carrier slide 101 thru the link 11 1 and adjustable connection with the slot 119 of the fixed plate 98, and simultaneouslywith such movement, the segment arm 111 will actuate the rack 108 to cause movement of the thick gage to or from Work-engaging position.

1 ,When driving tacks or fastenings with the thin gage 103 in use, the tacksare driven at a distance from the edge of the shoe determined by adjustment bodily of the plate 98 and. gage carrier slide 101, the thick edge gage being then in inoperative or lowered position. When the thick edge gage is moved to operative position, the slide 101 should be moved rearwardly a distance equal to the difierence between the distance from the shoe edge at which tacks are driven when the thin gage is in position and the dis tance from the shoe edge at which tacks are driven when the thick gage is in position, plus the amount that the thick gage projects forwardly of the thin gage. In the construction shown herein these adjustments are effected, as follows: To adjust the thin edge gage to the desired position relative to the.

driver path, the hand-piece 58 is manipulated to move the thick gage out of operative loosened and the fixed plate 98 together with the gage carrier'101 and its connectedrparts,

are moved to place the thin edge gage 103 in proper position. The thick edge gage is then adjusted by swinging the hand piece 58 to place the parts in the position indicated in Fig. 7. The block 117 is then loosened from its-connection with the bolt 112 as by manipulation of the nut 120 and is moved lengthwise to place the thick edge gage in the desired position, it being understood that owing to the inclination of the slot 119, such endwise movement of the block 117 will cause movement of the gage carrier slide 101. The parts being adjusted in the desired position, the block 117 is clamped in place. Thereafter, by manipulation of the hand-piece 58 as hereinbetore described, to change the kind or size of tacks or fastenings to be supplied, the appropriate edge gage is presented to the work, and located to cause the fastenings to be driven at the proper distance from the edge of the last.
